Aircraft ventral fairing partition wall and aircraft equipped with a ventral fairing

Abstract

The invention concerns a wall (10) of vertical partitioning for a ventral cowling of an aircraft including a plurality of vertical panels (11, 12, 12′, 13, 13′), each panel being linked to an adjacent panel by a vertical post (14, 15, 16). At least one exterior panel (13, 13′) is mounted in a fixed manner on at least one associated vertical post (14, 16). The upper end of said vertical post is fitted with a means of fastening in transverse rotation intended to be fixed to the structure (8) of an aircraft, the means of fastening in transverse rotation being capable of allowing the displacement (Dy) of the structure of the aircraft with respect to the fixed partitioning wall. It is also possible for at least one intermediary panel (12, 12′) to be mounted floating on at least one associated vertical post (15, 16), in such a way as to have a deflection parallel and perpendicular to the adjacent panels.

1. A ventral cowling of an aircraft having a wall ( 10 ) of vertical partitioning including a plurality of vertical panels, each panel being linked to an adjacent panel by means of a vertical post, characterized by the fact that at least one exterior panel, located at one end of the partitioning wall, is mounted in a fixed manner onto at least one associated vertical post, the upper end of said associated vertical post being fitted with a means of fastening in transverse rotation intended to be fixed to the structure of an aircraft, the means of fastening in transverse rotation being capable of allowing for displacement of the structure of the aircraft with respect to the fixed partitioning wall. 
     
     
       2. A vertical partitioning wall according to the  claim 1 , characterized by the fact that at least one vertical post associated with an exterior panel includes a means of fastening in translation intended to be linked to the structure of the aircraft, in such a way as to take up the axial forces to which the exterior panel is subjected. 
     
     
       3. A vertical partitioning wall according to  claim 1 , characterized by the fact that at least one intermediary panel, disposed between an exterior panel and a central panel, is mounted floating on at least one associated vertical post, in such a way as to have a deflection parallel to and perpendicular to the adjacent panels. 
     
     
       4. A vertical partitioning wall according to  claim 3 , characterized by the fact that the upper end and the lower end of at least one vertical post associated with an intermediary panel are fitted with means of fastening in axial rotation, intended to be fixed respectively to the structure of the aircraft and the ventral cowling. 
     
     
       5. A partitioning wall according to  claim 1 , characterized by the fact that it includes a central panel mounted in a fixed manner on two associated vertical posts which frame it. 
     
     
       6. An aircraft fitted with a ventral cowling according to  claim 1 , located below the wing box of the aircraft, at the junction between the wing surface and the fuselage of the aircraft, in which the vertical panels of the partitioning walls are mounted in a fixed manner on the bed of the ventral cowling. 
     
     
       7. A aircraft according to  claim 6 , characterized by the fact that the upper end of at least one vertical post associated with an exterior panel of the partitioning wall is mounted in transverse rotation onto the wing box of the aircraft, in such a way as to allow for elongation of said wing box parallel to the transverse axis of the aircraft. 
     
     
       8. An aircraft according to  claim 6 , characterized by the fact that at least one vertical post associated with an exterior panel of the vertical partitioning wall is linked in translation to the wing box, in such a way as to take up the axial forces to which said exterior panel is subjected. 
     
     
       9. An aircraft according to  claim 6 , characterized by the fact that the upper end and the lower end of at least one vertical post associated with an intermediary panel of the vertical partitioning wall are mounted in axial rotation, respectively, onto the wing box and onto the bed of the ventral cowling, in such a way as to take up the axial forces to which said intermediary panel is subjected. 
     
     
       10. An aircraft according to  claim 6 , characterized by the fact that the partitioning wall is linked to the wing box by longitudinal beams extending parallel to the longitudinal axis of the aircraft.
